STALL CONSTRUCTION.

Application filed July 3,

This invention relates to improvements in stall constructions and moreparticularly to improved stanchion operating and con trolling means,-oneobject 01" my present invention being to provide simple mechanism whichwill facilitate easy adjustment of the stanchion and operating meansforwardly or backwardly to align the cattle with the gutter.

A further object is to provide improved latching means in the operatingmechanism for a stanchion.

A further object is to provide, in stanchion operating mechanism,latching and stanchion opening and closing means which may be employedin the simultaneous operation of a plurality of stanchions but whichwill permit of any one or more 01 the stanchions being locked in closedposition and all the othersopened simultaneously.

lVith these and other objects in view, the invention consists in certainnovel features of construction and combinations of parts as hereinafterset forth and pointed out in the claims.

In the accompanying drawings,

Figure 1 is a view in elevation showing an embodiment of my invention.

Figure 2 is an enlarged view partly broken away, showing the positionswhich the parts assume when a stanchion is open.

Figure 3 is a view partly in elevation and partly in section showing thepositions of the parts when the stanchion is closed, and

Figure 4 is a sectional view on the line 4i& of Figure 3.

In Figure 1 of the drawing I have shown three stall posts 1-1-1representing two stalls 22, but it will of course be understood that anydesired number of stalls may be employed. The posts 1 support, throughthe medium of brackets 3, a rail 4 which is.

preferably angular in cross-section and said brackets are provided withupward extensions forming guides 5 for an operating rod (3. A stanchion7 is provided for each stall and may comprise an upright member 8 havinga rigid horizontal member 9 at its upper end and a rigid horizontalmember 10 at its lower end and a member 11 having pivotal or hingedconnection at its lower end with the lower member 10. A slide 12 ismounted on the upper horizontal stanchion mem ber 9 and has pivotallyconnected therewith a rod 13 which telescopes into the tubular 1923.Serial No. 549.261.

upper end portion of the hinged stanchion member 11. The lower end ofeach stanchion is connected as at 1 1 with a bottom bracket l5,.theconstruction being such as to permit adjustment of the bottom portion ofthe stanchion longitudinally of the stall and such construction may besubstantially that fully shown and described in Patent No. 1,415,117granted to me May 9, .1922. The upper horizontal bar 9 of the stanchionhas secured thereto a bracket 16 and this bracket carries aswivel 17adjustably connected with a bracket 18 secured to the rail 4. Theconnection of the stanchion with the rail 4 through the medium of thebracket 18 is such as to permit adjustment of the upper portion of thestanchion longitudinally of the stall and the said adjustable connectionmay be such as fully shown and described in my former Patent No.1,10et,057 granted January 17, 1922.

A slide 19 is mounted on the supporting rail and also has connectedtherewith, by means of bolts 20, a clamp 21 secured to the operating rodor bar 6. The slide 19 carries the opening and closing mechanism for thestanchion, and by providing the guides 5 for the operating rod, bindingof the slide 19 connected with said operating rod, on the rail 4; willbe prevented should the animal crowd in the stall and tend to causetwisting of the slide.

The slide comprises two members and the lower member 22 of said slidemay be made an integral part of a slide bracket 23. This bracket iselongated in shape and includes a plurality of spaced depending arms orprojections 24: between any two of which, a latch yoke 25 may bepivotally supported by a removable pin 26 passing through suitablealigning holes in said depending arms or projections. The pivot pin 26is provided at one end with an arm 27 to be disposed in an open notch orrecess 28 formed by an arm 29 at one end of the bracket 23, and said arm29 is made with a slot 30 open at one end. By connecting the latch yoke25 with the slide bracket as above explained, said yoke may be readilyadjusted longitudinally of the stall when the stanchion is adjusted toalign a particular animal with the gutter. The pivot pin 26 wi'il beheld normally against displacement by reason of the normal position ofthe arm 27 of the pin in the recess 28, out of alignment with the openslot 30, but when it becomes necessary to etlect adjustment of thelatch, the pin 26 will be turned to align the arm 27 with the slot 30and then 'ithdraw said pin to permit the latch yoke to be adjusted. Thepivot pin may then be adjusted.

The latch yoke 25 projects over the slide 12 with which the hingedmember 11 of the stanchion is connected and is provided with a wide endportion 25 having a curved slot 25 which receives a pin 31 projectingfrom the stanchion slide 12,such pin and slot connection permittinglimited turning movement of the stanchion without danger of the yokebecoming disengaged from the pin 31. hen the parts are in thesepositions (as shown in Figures 3 and 4) the stanchion will be in itsclosed latched position and will be retained in such position by reasonof the construction and arrangement of the mechanism employed forcontrolling the operation of the stanchion opening and closing devices.This mechanism includes a. "slotted hand lever 32 mounted on a pin 33supported by a bracket 31 on the stall post 1 at one end of the seriesof stalls. An arm or crank 35 (disposed normally at right angles to saidlever) is also mounted on the pin 33 and provided with a notch 36 to beengaged by a lug 36 on the lever. A. red 37 is pivotally connected atone end with the arm or crank 35 and at its other end this rod ispivotally connected with the operating rod or bar 6. It is evident thatwhen the arm or crank 35 is in the position as shown in Figure 1, theslide bracket 23 will be prevented from, moving and hence the stanchionwill be held in closed position. By moving the hand lever 32 upwardly toengage the lug 36 in the notch 36 in the arm or crank and then raisingsaid hand lever, motion will be imparted, through the medium ot thecrank arm 35, rod 37 and operating rod or bar 6 to the slide brackets 23and thus effect the opening of the stanchions, and a reverse operationof the hand lever will cause the stanchions to be closed. After thelever shall have been operated to open the stanchions, it may bedisengaged from the crank arm and permitted or be made to depend fromthe pin T he pivoting of the latch yoke to the slide bracket will causeit to accommodate any vertical movements of the stanchion causec bymovements of the animal but in order to prevent possibility ofaccidental disengagement of the latch yok from the pin 31, I provide theyoke with upwardly projecting stop lugs 38 disposed under a dependingstop plate 39 pivotally supported by the slide bracket 23. The pivot pin4:0 to which the stop plate is secured, is provided at one end with anarm 41 to permit the operator to turn said pin and raise the stop plate39 for a purpose hereinafter explained. The

latch yoke is provided rearwardly of its pivotal support, witn a toe 42which is normally engaged by a pivotally supported depending stop plate43, the, latter being carried by the slide bracket 23 and its pivot pin44 being provided with an arm 45 to permit said stop plate to be readilymanipulated.

Should all the stanchions ot' the series be connected, through the latchyokes, with the several slide brackets, in the manner shown in Figures 3and l and at the left of Figure 1, manipulation ot the hand lever 32would cause all the stanchions to be opened simultaneously and reversemovement of said lever would cause them all to be closed simultaneously.It sometimes happens how ever, that it desired to retain one or moreanimals in its stall and to release all the others. In such case, itwill be necessary to raise the latch yoke tor the stanchion which is toremain closed so as to disconnect said latch yoke from its hingedstanchion member and thus prevent this particular stanchion from beingopened when the others are opened. Before the latch can be raisedsui'iiciently to tree it from the pin 31, the stop plate 39 must firstbe raised. When the latch yoke shall have been released from the pin 31,the stop plate 4:3 will become disposed over the toe 42 of the latchyoke and retain the latter in the raised position indicated at the rightoi Figure l. The latch yoke having been disconnected from the hingedmember of the stanchion, the stanchion although closed, will beunlocked. It important however, that it be locked in closed position,and to accomplish this, an approximately U-shaped lock bolt 46 ismounted on each stanchion bracket 16 and maintained normally in idleposition by means of a spring all. The slide 12 with which the hingedmember is connected is provided at its sides with sockets l8 and whenthe stanchion is to be locked with the use of the lock bolt 4.6, saidbolt will be thrown over from the position shown in Figure l and at theleft of Figure 1 and caused to engage in one of the sockets 48 in theslide 12 as indicated at the right of Figure 1. The reason for providingtwo diametrically opposite sockets 48 is that it is sometimes desirableto dispose the lock bolt a l; opposite to the position shown in thedrawings.

With my improvements, the stanchions may be readily manipulated andeasily adjusted to align the animals relatively to the stall gutter.
